What is the maximum indicated airspeed allowed below 10,000 feet MSL?

Explanation:
Below 10,000 feet MSL, the limit is 250 knots indicated airspeed. This restriction is a regulatory speed cap (IAS) that applies to most operations to help ensure adequate maneuverability, provide a safe margin for stall characteristics, and reduce exposure to wake turbulence and noise near populated areas. Since the limit uses indicated airspeed, it stays the same on the instrument readout regardless of altitude, even though true airspeed can rise with altitude. So 250 knots is the maximum you may fly at or below 10,000 feet MSL. A speed of 240 knots is within the limit but not the maximum, while 260 and 270 knots would exceed the limit and not be permitted.
